CO-ORDINATION OF CLASSIFICATIONS FOR PRODUCT MODELLING AND ESTABLISHED BUILDING CLASSIFICATIONS A. EKHOLM Computer Aided Architectural Design, Lund Institute of Technology/Lund University, Lund, Sweden Abstract Computer based information management introduces new possibilities and puts partly new requirements on information and classification systems. The rapid develop-ment and dissemination of information technology within the construction sector demands international co-ordination of standards and classification systems. This paper presents the preliminary results of a study of the product model classification systems IFC and POSC/Caesar in relation to the established building classification systems as defined in ISO 12006-2 and the Swedish BSAB 96. The study is part of a project with the aim to analyse the structure, scope and direction of development for these different systems, and to investigate the possibilities of co-ordination and co-operation between them. It shows a need for co-ordination of concepts in the ontological and the domain levels. Keywords: CAD, design, databases, building classification, interoperability. 1 Introduction 1.1 Co-ordination of systems for information sharing The rapid development and dissemination of information technology within the construction sector demands international co-ordination of standards and classification systems. Computer based information management introduces new possibilities and puts partly new requirements on classification systems. This paper reports some preliminary results of an ongoing investigation of the prerequisites for co-ordinating classification systems for product modelling in the construction context, with established building classification systems. The study is financed by the Swedish national research program ”IT ByggFastighet 2002” (IT Con
